Pi can be defined as an unbounded rational

This article extends the definition of unbounded rational numbers established in my previous work, Every Real Number Can Be Expressed as an Unbounded Rational Number, to accommodate any chosen method for defining the integer part. While 𝜋 is typically defined as the ratio of a circle’s circumference to its diameter [1], it can also be expressed as an unbounded rational, inviting reconsideration of its traditional classification as irrational.
